Adds a new method, IGBP::detachNextBuffer, that effectively does dequeue + request + detach in a single call, but does not need to know anything about the dequeued buffer, and will not block on dequeue. This is mostly for the upcoming StreamSplitter to use in its onBufferReleased callback. Change-Id: Ie88a69de109003acebaa486a5b44c8a455726550
